It's impressive that he shoots as well as he does from deep, but honestly I think this chase is mostly a reflection of the fact that he's taking nearly eight threes per game.
Ray took 8.4 the year he set the record. You've gotta take a lot to make a lot, but I'd say shooting 45.5% at that kind of volume makes it even more impressive.
I agree. You hear people try to argue that Nash or Dirk are the best shooters of this era with their pretty percentages. And lack of volume doesn't take anything away from guys like Nash, Dirk, and Bird. They could be better shooters than Ray for all anybody knows. But they can't say they're the best in-game shooter ever like Ray can. They don't have that much proof.
As for Curry, if he breaks the record I don't think I can quite say it was as impressive as when Ray did it. Not even taking pace into consideration, Ray didn't have a down low presence to draw in the defense, let alone a beast like David Lee who can triple threat and cause a double team (also more than willing to pass back out with 3.4 assists a game). Ray on the other hand was the one getting double teammed with bigs like Wilcox, Radmanovic, Collison, Petro, Reggie Evans, and Mikki Moore. It's also fair to say if born two inches shorter and played PG with a green light for pull-ups he would have taken a lot more 3s.
